IdenTrust: ICA with invalid CDP
IdenTrust issued a subordinate CA certificate on September 15, 2025, which contained an invalid Certificate Revocation List (CRL) Distribution Point (CDP). The error was identified the following day, leading to the certificate's revocation on September 17, 2025. The mis-issuance was due to an incorrect value being copied into the certificate profile, which went undetected due to a lack of enforcement in the approval workflow. No end-entity certificates were issued from this CA, thus no relying parties were affected. IdenTrust has since implemented a systematic enforcement mechanism to ensure all certificate profiles undergo proper review before issuance.
